The investigators will record their findings on data collection forms. The primary outcome will be nausea as measured on a 10 cm visual analogue scale (VAS) at 30 minutes. Nausea measurements will also be collected at 10, 20, 40, 50, and 60 minutes, and then every hour up to 5 hours, then at disposition at which time the patient will provide one final nausea VAS score. The study team member will not be present in the patient's room during the intervals between these evaluations. At the time of each nausea measurement, patients will be offered another preparation pad (up to ten pads). Investigators will notify the patient's treating provider to prompt consideration for treatment with a rescue anti-emetic (such as metoclopramide or promethazine) if the patient vomits or if the patient requests an anti-emetic at any time. At the time of each nausea measurement, a pain score will also be measured on a 10 cm VAS. At the time of final disposition, the patient will provide a satisfaction score on a 10-cm VAS and be asked to indicate his/her belief as to whether the pad was a treatment or placebo and whether the oral solution was a treatment or placebo. Similarly, at study conclusion the patient's provider will be asked to indicate his/her belief as to whether the pad was a treatment or placebo and whether the oral solution was a treatment or placebo. Other data collected will include times and doses for all medications (including preparation pads) and fluids administered, episodes of vomiting (defined as forceful expulsion of gastric contents separated by at least 2 minutes), disposition (admission versus discharge), final clinical impression at the time of disposition, and time to disposition. Subjects will be followed and data collected for the entirety of their ED stay.
